Antimicrobial resistance is one of the greatest threats facing humanity, making the need for new antibiotics more critical than ever. While most antibiotics originate from bacteria and fungi, archaea offer a largely untapped reservoir for antibiotic discovery. In this study, we leveraged deep learning to systematically explore the archaeome, uncovering promising candidates for combating antimicrobial resistance. By mining 233 archaeal proteomes, we identified 12,623 molecules with potential antimicrobial activity. These peptide compounds, termed archaeasins, have unique compositional features that differentiate them from traditional antimicrobial peptides, including a distinct amino acid profile. We synthesized 80 archaeasins, 93% of which showed antimicrobial activity in vitro against Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus spp. Notably, in vivo validation identified archaeasin-73 as a lead candidate, significantly reducing A. baumannii loads in mouse infection models, with effectiveness comparable to that of established antibiotics such as polymyxin B. Our findings highlight the potential of archaea as a resource for developing next-generation antibiotics. Use of artificial intelligence to mine proteomes of archaea led to the discovery of archaeasins, antimicrobials that kill drug-resistant bacteria in laboratory and animal models, offering a promising source of future antibiotics.

The immune system permeates and regulates organs and tissues across the body, and has diverse roles beyond pathogen control, including in development, tissue homeostasis and repair. The reshaping of the immune system that occurs during aging is therefore highly consequential. In this Focus issue, Nature Aging presents a collection of reviews of and opinions on recent advances in research into immune aging.

🦠 La liste OMS 2024 des bactéries les plus préoccupantes vient d'être publiée dans le Lancet infectious disease https://lnkd.in/eYmnPyAm
💬 Elle est établie par la consultation d'expert du secteur chargée de scorer chaque bactérie selon 8 critères (mortalité, contagiosité, incidence, traitements disponibles etc voir les items en haut de la figure)
Quelques commentaires par rapport au classement 2017 :
- Les bactéries à gram négatif continuent de dominer largement le classement
- Les entérobactéries ont pris les 2 premières places (occupées en 2017 par Acinetobacter et Pseudomonas) ce n'est pas un détail, les entérobactéries sont des bactéries "communautaires" alors que Acineto et Pseudomonas sont essentiellement retrouvées dans les infections hospitalière
- Ainsi les Klebsielles résistantes aux carbapénèmes est maintenant l'espèce bactérienne qui préoccupe le plus, souvent resistante à tous les antibiotiques et très virulentes (on voit son score de mortalité et sa difficulté de traitement élevé sur la figure)
- La tuberculose résistante a été rajoutée et apparait au rang n°4
💡 Ce classement est un bon outil
pour les décideurs pour cibler la recherche anti-bactérienne sur les problèmes les plus importants
et pour le public/les journalistes pour savoir comment interpréter certaines annonces "spectaculaires" de découverte de nouveaux traitements en fonction de la bactérie concernée
